- W2227561750 abstract "The micro circulation system which is distributed in the entire body plays an important role in maintaining the metabolism and transport nutrients and wastes. In addition, the hemodynamic characteristics of blood flow such as wall shear stress and flow rate are important factors that affect angiogenetic process and control the vasomotion and dilatation of the vessel adaptively. These factors of blood flow in the micro circulation system are crucial in the development of the cardiovascular system as well as for the proper functioning of an organism, especially when the blood flow is related to circulatory diseases. Moreover, the structural characteristics of blood vessels (Murray’s law and bifurcation pattern) are significantly influenced by blood flow. Therefore, it is important to measure the blood flow in vivo and determine its relation to the structural rules of the vessel. In this study, we measured the blood flow in the extraembryonic arterial blood vessels of chicken embryos and correlated the hemodynamic characteristics and the structural rules of the vessels along the bifurcation cascade. Blood flow was measured using a micro-PIV technique and the temporal characteristics of the flow were obtained using a high-speed CMOS camera. The mean velocity in the arterial blood vessels was observed to decrease and Womersley number (α) calculated based on the pulsating frequency and diameter of the vessel also decreased as the bifurcation cascaded. The ratio of Murray’s law (= D?³/(D₁³ + D₂³), where D?, D₁, and D₂ are the diameters of the parent and two daughter vessels, respectively) was very close to the theoretical value of 1 when the vessel diameter was small (50 ㎛ ≤ D? ≤ 100 ㎛). However, the value deviated from 1 as D? increased. The bifurcation angles were wider when the D? was smaller and became narrower as D? increased. These results indicate that Poiseuille’s formula is best approximated for smaller vessels (when Womersley number approaches to zero)." @default.
